Safety1. Overcurrent protectionWhen the current increasing in an exception, power bank immediately Start voltage buffer fuction, ensure the voltage in a steady state at any time., Avoid cause your charging device any damage.2. Short circuit protectionWhen there is a short circuit occur in external device, power bank start Protection function, shut down the supply and avoid short circuit damage.3. Overheat protectionWhen the power bank work long in high temperature environments (Exceed 60 degrees), Power bank will not be dangerous due to the high temperatures.4. Overdischarge protectionWhen power bank discharge reached the critical point, the circuit automatic start Protection function and stop discharge.5. Overcharge protectionLong time charge for mobile power supply or use power bank charge for the phone. When reach saturation point, system automatically shut down, avoiding the overload problems.6. Overvoltage protectionLong time charge for mobile power supply or use power bank charge for the phone, When reach saturation point, in order to prevent over-voltage, the system automatically turns off.
